From: Andreas Krebbel Date: Mon, 10 Oct 2016 15:09:03 +0000 (+0200) Subject: S/390: Move binary start to 16M. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=82057c771e4338fd47d1ce570f29040186c51f9b;p=binutils-gdb.git S/390: Move binary start to 16M. Turned out that by moving the binary start to 256M I've hit a case with potentially a lot of aliasing in the branch target buffer between binaries and shared libs. So moving on. Tested on s390x.
